Mortgage renewal can be a complex process, and many Canadians miss opportunities by automatically renewing without research. Key tips include researching current rates, negotiating with lenders, and understanding the implications of the lowest rates. Consider making extra payments towards the principal and leveraging home equity for projects. Using a mortgage broker may yield better rates, and switching lenders shouldn't be daunting due to potential discharge fees. Start the renewal process early and seek advice tailored to educators for optimal results.
